The whole fact of propaganda in the media is manipulation, and subliminal messaging, full time. There's all kinds of subliminal messaging including certain frequencies that information can be hidden in coming from certain shows watched on tv and smartphones that we can't even hear or know it's even happening. Colour patterns And the way that they are moving on the screen can put the viewer into a kind of trance. Just the talking points that are used are basic power of suggestion. It's an onslaught of manipulation all the time, and hardly anyone sees it, or believes it's happening.

There are certain books that are essential reading for understanding how the masses are manipulated.

First of all, if you're not familiar with Edward Bernays, then learn about him and read some of his books. This will give you a good general grounding in the history and evolution of mass-manipulation techniques. For the visual side of things, I would highly recommend reading the book 'Amusing Ourselves to Death' by Neil Postman. If you're interested in current techniques being used by advertisers and marketeers, then check out the book 'Black Ops Advertising' by Mara Einstein.
